Fatbikes aren't for everyone but I can tell you that for those who do, they're a blast. I own two and ride them yearround fulltime. I might as well sell the enduro for how little it gets used anymore.

Setup advice - all pretty specific and might not apply so YMMV:

1.) Some guys like wider bars and short stems for more control than what comes stock. Grips upgrade too. Coming from a moto background you might concur.
2.) If you're in a cold, snowy climate good flat pedals and properly insulated boots could be a good choice over SPDs and mtb shoes that clog with ice more.
3.) Tires/rims upgrade. Wider is better if you're a heavier rider on deeper ungroomed snowy trails a lot. If you weigh less and/or are in a dry warmer climate and/or always on groomed packed snow go narrower for weight reduction and speed.
4.) If you deal with icy trails a lot- get studded tires - either Gripstud/Koldkutter them yourself or break the bank and get prestudded Dillinger 5s, etc. Throw some on your boots too. One bad crash on ice without studs will make you wish you had.
5.) In deeper snow, let more air out than you think you should. 4-5 psi could be good. Too many guys ride too high a psi in fatbike tires in deep snow and have a bad time. Get used to monitoring conditions and adjusting psi - even one pound makes a big difference in fatbiking.
6.) If you're in a cold climate get some footwarmers for the boots, insulated socks, balaclava, proper layering and shell, pogies, and good insulated gloves.
7.) Try to stay off roads that get salted as much as possible. Too much of that can be really destructive to a nice fatbike.

If you really get into fatbiking you'll start to embrace the long dreary winters there as long as there's snow.

Agreed, this is my first winter on a fat bike and in a long northern New England winter I have never been happy. I look forward to get out every chance I can. Now I even look forward to snowshoeing after storms to help pack the trails. It's amazing what getting outdoors in the winter can do for your attitude.
